Base station, service providing device, user equipment, mobile communication system, and communication control method therefor
First Claim
1. A base station comprising:
- a first communication unit that wirelessly communicates with a user equipment;
a second communication unit that communicates with a service providing device for providing a service corresponding to a location of the user equipment; and
a control unit that controls the first and second communication units,wherein the control unit is configured to;
in response to one request from the service providing device, instruct the user equipment to perform a first measurement on a reception status of a radio signal from the own base station, and indicate to the user equipment a number of reports for the user equipment to report a result of the first measurement, the number of reports being requested by the service providing device;
further instruct, in response to the one request, the user equipment to report a result of a second measurement on a reception status of a radio signal from a first base station disposed adjacent to the own base station for the number of reports, and to perform the second measurement in accordance with a predetermined condition for measurement;
further instruct, in response to the one request, the user equipment to report a result of a third measurement on a reception status of a radio signal from a second base station disposed adjacent to the own base station for the number of reports, and to perform the third measurement regardless of the predetermined condition for measurement;
sequentially notify the service providing device of the result of the first measurement to the third measurement reported from the user equipment for the number of reports; and
autonomously complete a response to the one request when the notification is performed for the number of reports.

Abstract
In order to improve utilization efficiency of communication resources in a case of acquiring a reception status at a user equipment of a radio signal upon providing LCS, an E-SMLC (40) forming a mobile communication system requests an eNB (10) to notify a result of measurement on a reception status at a UE (20) of a radio signal at least from the eNB (10) for a predetermined number of times. The E-SMLC (40) calculates a location of the UE (20) using the result of the measurement when the notification is performed for the number of times, and provides a service corresponding to the location. In response to the request, the eNB (10) instructs the UE (20) to perform the measurement for the number of times and sequentially notifies the E-SMLC (40) of the result of the measurement reported from the UE (20) for the number of times. The UE (20) performs measurement on the reception status for the number of times and sequentially notifies the eNB (10) of the result of the measurement for the number of times.
